We are happy to announce the early RFC version of the Arm Confidential Compute Architecture (CCA) support for the Linux stack. The intention is to seek early feedback in the following areas: * KVM integration of the Arm CCA * KVM UABI for managing the Realms, seeking to generalise the operations wherever possible with other Confidential Compute solutions.A prototype for launching Realm VMs with QEMU is available at: https://lore.kernel.org/qemu-devel/20230127150727.612594-1-jean-philippe@linaro.org/ (local) Thanks, Jean
Hi Jean, I've tried your series in Real on CCA Host, but the KVM arch init emits an Invalid argument error and terminates. I configure it with the aarch64-softmmu target only and built, any other steps I should worry? Itaru.
